DETROIT, Mich. — General Motors announced a recall on numerous 2019 model year trucks and sedans due to a braking issue. General Motors already issued a recall for these vehicles. However, the repairs exposed another fault in the braking systems. Each recall involves a software glitch. Approximately 500,000 vehicles are affected by this announcement, according to Yahoo. Not every vehicle recalled during the first wave received the repairs and have not experienced the braking problem associated with that fix. Owners of vehicles whose cars have not had any recall updates will receive the latest update that will patch both problems. GM did not provide a timeframe for the completion of the recall program.
GM’s first software repair for their 2019 Chevy Silverado 1500 pickups, Cadillac CT6, as well as the GMC Sierra 1500 repaired a software problem that disabled the anti-lock braking system. The glitch would prevent the vehicles’ electronic stability control system from activating. The software problem stopped the vehicles’ computers from accurately communicating how those systems functioned. Unbeknownst to the driver, the software glitches meant that the vehicle might not brake correctly. GM said that these vehicles could lose braking functions, partially if not completely.
The repair for the software problem touched off another round of braking problems. The patch overcompensates for the malfunction. GM learned that the patch could apply the vehicles’ brakes even though the operator did not apply them. The vehicle, therefore, could stop without warning and without any apparent reason to anyone else sharing the road with the defective GM car or truck.
GM rolled out the first patch recently and has not repaired that many vehicles. All vehicles subject to the first recall campaign are still subject to the same recall. However, the cars and trucks that have not received any patch will receive the latest patch that will repair both problems. Vehicles that received the first patch must return to the dealership to download the latest software patch.
